STAND-PIPE FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 273,031, dated February27, 1883. Application filed March 15, 1882. {No modell To all whom "itmay concern Be it known that I, JOHN T. COWLES, residing in Chicago, inthe county of Cook and State of Illinois, and a citizen of the UnitedStates, have invented a new and useful Injprovement in Stand-Pipes forBuildings, of which the following is a full description, reference beingbad to the accompanying drawings, in which- Figure l is a frontelevation, and- Fig. 2 a detail section taken on the line as m, Fig. 1.

My improven'ient relates to that class of stand-pipes which are attachedto buildings, the stand-pipe having a hose-coupling at the (lifl'erentstories of the building, to which firemen can attach their hose for thepurpose of extinguishingtires in a building, and to which ladders areordinarily attached both for the firemen to ascend and for the occupantsof the building toescape therefrom in case of tire.

My invention consists in the particular man nor of attaching the valveto the stand-pipe, as hereinatter more fully described and claimed.

In the manufacture of these stand-pipes, which I have been engaged 'inmaking and applying for several years, they have heretofore been made inSections, with a T-valve section inserted in the pipe at the differentstories where it is desired to couple a hose. This T'- section makes arecess or chamber in the pipe, which impedesthe tlow of water and alsomakes projecting shoulders, to which it is difficult to fit a ladder. Itis necessary to measure the building and have the stand-pipe fitted withthe T-valves at intervals, according to the different heights of thestories of the buildings, which is quite expensive, in addition to theobjections above referred to. My improvement enables me to have thestand-pipe in a single piece the entire height of the building,

[ sents a stand-pipe which extends the entire height of the building inone continuous piece.

Dare holes cut in one side of the standpipe, at such points as I Wish toattach a valve to the stand-pipe contiguous to each story of thebuilding. (3 is the valve-case, with the coupling-nozzle D, suitablyconstructed to admit of the hose being coupled thereto in the ordinarymanner.

E is the valve, which is raised and lowered by means of the screw F. Thevalve-case has a flange, G, which fits to the outside surface of thestand-pipe, and is bolted to the standpipe by screw-bolts H.

I is a packing between the flange and the stand-pipe to make atightjoint. This valve, with its hose-coupling, can be readily attachedto the stand-pipe at any point, even after it is attached to a building.The valves may have the ordinary packing, or- I may make the valve-caselarger than the hole in the pipe, so that the pipe itself may form avalve-seat, the valve being also a little larger than the hole in thepipe. This construction would prevent any leaking around the joint whenthe valve is not in use.

J is the side piece of theladder, which is secured to the stand-pipe,and is a straight continuous piece fitted against the stand-pipe. Therebeing no shoulders or T-valves in the stand-pipe, it is a straightcontinuous piece, requiring no bending or breaks to fit closely receivesthe rungs of the ladder in the usual manner.

'It will be readily understood that by constructing my stand-pipe andladder in the manner above described I am enabled to order a continuouspiece. of pipe suitable for a stand-pipe adapted to reach to the top ofa building, and apply the valves and the hosecouplings in a cheap andefficient manner to the stand-pipe at such points as may be required toadapt it to the particular building, according to the height that thestories may happen to be. There are no recesses or chambers in the pipeto impede the flow of water, and no shoulders or Ts on the pipe tointerfere with the fitting of the ladder thereto.

against the side of the stand-pipe. This strip Having thus described myimprovement, packing I, all constructed and combined to what; I claim asnew, and desire to secure by operate substantially as and for thepurpose Letters Patent, isherein shown and set; forth.
